Which PICs are the new M2 chips based on?

Ok, I am curious. Which Microchip PIC microcontrollers are the new Picaxe 08M2, 14M2, and 20M2 based on?

Searching the forum, in particular new threads about the chips you ask about can be helpful.

For the 18M2 that has also been discussed here shortly after it's release - try a search

Closely read the post by Technical.

...and then read between the lines. I have all the information I need.

Try the Microchip Product selector, given that the 08M2 is 8pins and 1.8v to 5v operation, there are not many choices ........

I thought Rev-Ed had a deal worked to have a private chip with just there name and revision numbers on the M2 series. Was I mistaken? Please set me straight if I got that info wrong. Thanks!

I don't know what a "private chip" is, but Rev-Ed is pretty obviously (IMHO) saying, via a variety of phrases, that the M2 chips are more than just relabelled PICs.

Whether there are silicon die changes, internal firmware changes or anything else is pretty much speculation without any official statements - which look unlikely to be forthcoming.

The 18M2 had a different development path to the later M2 chips, so the situation is not the same for all M2 parts. We are not being difficult, it's just that we cannot legally say a sentence like "a PICAXE-20M2 labelled part is a PICxx" due to trademarks and agreements etc. etc.

Perhaps an easier explanation is as follows:

Thanks for the handy way to help identify those little SOIC PICAXE chips, Technical. My white dots were rubbing off.
